474光电倍增管用于双光子实验内探测器的合格试验
Qualification Tests of 474 Photomultiplier Tubes for the Inner Detector of the Double Chooz Experiment
摘要:
半球形10”光电倍增管(PMT)R7081,来自Hamamatsu Photonics K.K. (HPK)被用于粒子和天体粒子物理学的各种实验中。本文介绍了反应堆双中微子实验中474台光电倍增管的测试和标定。海德堡Max-Planck-Institut für Kernphysik Heidelberg(MPIK)的独特测试装置允许同时校准30个PMT,并表征单个光电子响应、渡越时间扩展、线性行为和饱和效应、光子探测效率和高压校准。
英文摘要:
The hemispherical 10" photomultiplier tube (PMT) R7081 from Hamamatsu Photonics K.K. (HPK) is used in various experiments in particle and astroparticle physics. We describe the test and calibration of 474 PMTs for the reactor antineutrino experiment Double Chooz. The unique test setup at Max-Planck-Institut für Kernphysik Heidelberg (MPIK) allows one to calibrate 30 PMTs simultaneously and to characterize the single photo electron response, transit time spread, linear behaviour and saturation effects, photon detection efficiency and high voltage calibration.
